Blue is a two motor four legged walker utilizing the microcore controller invented by Mark Tilden. Sensors include two photodiodes to give the bot photothropic behaviour by influencing the nervous net governing the walking gait. Power comes from twin Panasonic sunceram solarcells stored in a 1F capacitor. The bot has an on/off cycle of about 4 seconds/one minute in full sunshine, longer in lower light conditions as governed by an additional photodiode. Terrain handling ability is quite impressive. This bot has been seen attempting to climb over walls of its own height. Demonstrates how effective the nervous
net technology is as a controller for a legged machine.
